This is a mutually exclusive event because you can't choose both at the same turn you can only pick one or the other. so we add the event chances together,
5/35 + 10/35 = 15/35 or reduced 3/7

If the amount of air in a spherical balloon is 288 cu. in., what is the radius of the balloon? 6 inches 7.3 inches 72 inches
garik1379 [7]

Answer:

6in

Step-by-step explanation:

The volume of a spherical balloon is 4/3 π R^3.  

So 288π = 4/3 π R^3  

The factors of π cancel out. Divide both sides by 4/3 to get:  

216 cubic inches = R^3  

Take the cube root of both sides, and you find that R = 6 inches

No need to apologize, that's why we're here.

Rectangular prism, 25x10x8

The surface area is the sum of the area of all the surfaces.  We have 2 surfaces that are 25x10, two 25x8 and 2 10x8 so our total surface area is

2(25(10) + 25(8) + 10(8))=2(250+200+80)=2(530)=1060, choice B


Red marble, 15 out of 40, 15/40 = 3/8, choice B again


There's really not enough information to answer unless we assume the only ways Bart washes his car is the gas station or himself.  Assuming that, the probability he washes it himself is 1 minus the probability he washes at the gas station.

p = 1 - \frac 1 4 = \frac 3 4 = 75 \%, Choice D
